| Abstract: | A method based on integrals of motion for collective processes has been proposed for constructing physical schemes in which the state of one of the subsystems is insensitive to interaction. Decoherence-free quantum channels that allow transmission of an arbitrary light state including the Fock state through an absorbing medium are considered as an example. |
